So a few days ago I installed Zorin OS (basically, Ubuntu with a Windows-like desktop environment) on my grandmother's computer to save it from the slowness of Windows 7.
Now, since she uses an AT&T USB Modem (Sierra AirCard 313U) I have to load the sierra and sierra_net modules (since they're not loaded by default). So, I made this file in /etc/modprobe.d/sierra-wwan.conf:
#load Sierra kernel modules
install sierra /sbin/modprobe sierra
install sierra_net /sbin/modprobe sierra_net
Though, for some reason, it won't load the modules. After some hair pulling, I got desperate enough to just load the modules from an init.d script (yeah, I know you're supposed to use modprobe.d specifically for kernel modules, but I was desperate) and it contained this:
#/etc/init.d/sierra-wwan
#load Sierra kernel modules
#yeah, yeah, I know it's /etc/modprobe.d for kernel modules, don't judge me
modprobe sierra
modprobe sierra_net
Now, at least the modules load (as verified with lsmod | grep sierra), but the module won't actually do anything (i.e. recognize the modem, connect to AT&T, etc...) unless I login to my account, and reload the module with sudo modprobe -r sierra sierra_net; sudo modprobe sierra sierra_net, logout, and log my grandmother in again.
I have tried loading, then reloading using the init.d script (and with a modprobe.d conf), but it only works if I do it manually.
